I have a MimeMessage which contains a winmail.dat attachment of type application/ms-tnef.
I believe this is an RTF formatted email, which is sent from Outlook client. I tried parsing it with the tnefpart but I'm running into the following error.
Here is my function:
ProcessMimeMessage(MimeMessage plainMime)
{
foreach (var attachment in plainMime.Attachments)
{
if (attachment.GetType() == typeof(MimeKit.Tnef.TnefPart))
{
ReportStatus("Processing Tnef Part (RTF Message): ");
MimeKit.Tnef.TnefPart tnefPart = (MimeKit.Tnef.TnefPart)attachment;
try {
MimeMessage mimeMessage = tnetPart.ConvertToMessage();
} catch (Exception ex) {printexception(ex);}
}
}
}
This is the exception that is thrown from ConvertToMessage
Invalid addr-spec token at offset 0
at MimeKit.InternetAddress.TryParseAddrspec(Byte[] text, Int32& index, Int32 endIndex, Byte[] sentinels, Boolean throwOnError, String& addrspec, Int32& at)

Thanks
This just means that the "email address" in one of the TNEF fields is not a valid email address (syntactically).
It might just be that the address type field was not "SMTP" and MimeKit tried to parse it as if it were a rfc822 address field.
I've improved the robustness in the following commit: https://github.com/jstedfast/MimeKit/commit/15f955b49dc7743d1281afbedce6d327706e161b
You can use the MyGet packages listed in the README.md file to get the fix for this.

Yes, from Xamarin.Plugin.FilePicker,we know that :
This package has been deprecated as it is legacy and is no longer
maintained.
Just as SushiHangover said, you can use Xamarin.Essentials: File Picker to achieve this.
The FilePicker class lets a user pick a single or multiple files from the device.
FilePicker.PickAsync() method enables your user to pick a file from the device. You are able to specific different PickOptions when calling the method enabling you to specify the title to display and the file types the user is allowed to pick. By default.
You can refer to the following sample code:
async Task<FileResult> PickAndShow(PickOptions options)
{
try
{
var result = await FilePicker.PickAsync(options);
if (result != null)
{
Text = $"File Name: {result.FileName}";
if (result.FileName.EndsWith("jpg", StringComparison.OrdinalIgnoreCase) ||
result.FileName.EndsWith("png", StringComparison.OrdinalIgnoreCase))
{
var stream = await result.OpenReadAsync();
Image = ImageSource.FromStream(() => stream);
}
}
return result;
}
catch (Exception ex)
{
// The user canceled or something went wrong
}
return null;
}
Default file types are provided with FilePickerFileType.Images, FilePickerFileType.Png, and FilePickerFilerType.Videos. You can specify custom files types when creating the PickOptions and they can be customized per platform.
For more,check:https://learn.microsoft.com/en-us/xamarin/essentials/file-picker?context=xamarin%2Fxamarin-forms&tabs=android .
Update:
For how to open an existing file, you can refer: Xamarin.Essentials; FilePicker; Save a new file .
I'm using NReco.PdfGenerator for my PDF documents(that component is based on WkHtmlToPdf tool), my code allow me to create a pdf calling a function with the parameters controller, action, model:
public static byte[] GeneratePdfDocument(System.Web.Mvc.Controller controller, string viewName, object model)
{
string result;
controller.ViewData.Model = model;
using (StringWriter sw = new StringWriter())
{
ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(controller.ControllerContext, viewName);
ViewContext viewContext = new ViewContext(controller.ControllerContext, viewResult.View, controller.ViewData, controller.TempData, sw);
viewResult.View.Render(viewContext, sw);
result = sw.ToString();
}
return (new NReco.PdfGenerator.HtmlToPdfConverter()).GeneratePdf(result);
}
With this code I can create a PDF easily from my views and it's working great on my development environment but on a server I'm getting this error:
The pipe has been ended.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I think that is maybe a problem with permissions or some configuration on my IIS, any idea?
You are probably missing Visual C++ Redistributable Packages for VS2013 (x86). Even if your server is running 64bit Windows, you need to install the x86 C++ Packages.
I have a form that has a DropDownList. I am using SQLServer State mode to save the session in SQL Server. The form is displayed correctly; however, it throws an exception during the form submission. I've been looking and tried some of the suggested answer that were posted online with no luck. What am I doing wrong here?

I think you have too much here. Try changing your code this way
public IEnumerable<SelectListItem> DepartmentList { get; set; }
I usually use List but ienumerable should work too
then on your view you don't need to cast the list
#Html.DropDownListFor(model => model.DepartmentID, Model.DepartmentList, "Select Department", new {#class="form-control", id="DepartmentID", onchange = "ValueSelected()" })
the "for" helper will map the list for you. See if this helps
Hello I'm just searching for more than 2 days...
My problem: I want to send a Post Request to a Server and send a File (FileBody) with this post.
I've found many examples for this with the WebClient class. But I am a newbee to C# and Windows Phone development and so i did not get it to work. Because the only method i see is "UploadStringAsync" but the method mentioned everywhere in the internet "UploadFile" is not available in my object.
string postdata = string.Format("cmd={0}&", "show");
postdata += string.Format("latitude={0}&", HttpUtility.UrlEncode("-1"));
...
WebClient wc = new WebClient();
wc.UploadStringAsync(new Uri("http://mydomain/myphp.php", UriKind.Absolute), "POST", postdata);
The problem is i have to send a FileBody as mentioned here: http://www.codescales.com/category/howto/
But i cant reference this project to my windows phone project.
I am very confused right now and hope anyone can help me with this.
You can use RestSharp, (Nuget it)
Contains several options to upload files:
public IRestRequest AddFile(string name, string path);
public IRestRequest AddFile(string name, Action<System.IO.Stream> writer, string fileName);
public IRestRequest AddFile(string name, byte[] bytes, string fileName);
public IRestRequest AddFile(string name, Action<System.IO.Stream> writer, string fileName, string contentType);
public IRestRequest AddFile(string name, byte[] bytes, string fileName, string contentType);
When server side obtain a zip data package from client side.I unzip this package and parse xml data to sql server.Then return success message to client side!
but I run into problem. I woluld like to return success message to client side in time when client uploaded success but not after inserted into data to database!
Can you help me ？tks in advance! sorry for my bad english!
public IAsyncResult BeginAsyncUpload(string token, Stream data, string fileName, string Org, AsyncCallback callback, object asyncState)
{
if (BaseClass.HasPermission(token))
{
return new CompletedAsyncResult<Stream>(data, fileName,Org);
}
else
{
return null;
}
}
public string EndAsyncUpload(IAsyncResult ar)
{
Stream data = ((CompletedAsyncResult<Stream>)ar).Data;
string fileName = ((CompletedAsyncResult<Stream>)ar).FileName;
string Organization = ((CompletedAsyncResult<Stream>)ar).Org;
try
{
return _streamToFile(data, fileName, Organization);
}
catch
{
return "SUCCESS！";
}
}
THE _streamToFile method insert data into db
First thing is that you can seperate your database insertion code and call that funcation asynchronously.
refer for asynch http://msdn.microsoft.com/en-us/magazine/cc164036.aspx
Second method is, store file in folder A, create seperate win service application to read files from same folder A, extract and insert into sql.Then move to folder B.
